Steel Milling Grade Inserts Feature Advanced Coating and Substrate Technologies

Sandvik Coromant has expanded its CoroMill MS20 shoulder milling concept to include grade GC1230 inserts, specifically engineered for ISO P materials. This true, 90-degree shoulder milling solution delivers exceptional performance in steel machining, from roughing to finishing, with uncompromised security, versatility and productivity, the company says.

CoroMill MS20 combines high-quality cutter bodies with precision inserts to deliver excellent surface finishes and optimal wall quality in repeated shoulder milling. The robust cutter body provides tight tolerances on both axial and radial runout, enhancing component quality and reducing scrap rates. The inserts, manufactured using advanced pressing technology, offer greater dimensional accuracy, further enhancing insert tool life and component quality.

Steel milling grade GC1230 inserts feature advanced coating and substrate technologies that provide excellent wear resistance and edge line security. Users will benefit from predictable tool life and consistent performance, even in demanding conditions.

The CoroMill MS20 assortment includes cutter bodies ranging from 15.8 – 84 mm (with inch equivalents), along with a cylindrical shank option with Sandvik Coromant’s Silent Tools integrated damper, enhancing stability and performance in demanding operations. The insert range features geometries optimized for steel, stainless steel and heat-resistant super alloys.
